Answer:

125ft³

Step-by-step explanation

Given the area of the sail boat expressed as [tex]A = 16\sqrt[3]{d^2}[/tex]. IF the area is 400ft², we are to find the displacement d;

Substitute A = 400 into the expression given and find d as shown;

[tex]A = 16\sqrt[3]{d^2}\\400 = 16\sqrt[3]{d^2}\\400/16 = \sqrt[3]{d^2}\\cube \ both \ sides\\(400/16)^3=( \sqrt[3]{d^2})^3\\64,000,000/4096 = d^2\\d = \sqrt{64,000,000/4096} \\d = 8,000/64\\d = 125 ft^3[/tex]

Hence the displacement of the hull of the sailboat is 125ft³

Answer:

(8.75, 2.5)

Step-by-step explanation:

When they ask what point (n,a) corresponds to this, they want a coordinate with an x-value of 8.75.

If we look on the graph, we can see that the a value is around 2.5 quarts of strawberries, so for our point, we will write (8.75, 2.5)

Answer:

The null hypothesis is  [tex]H_o : \mu = 16[/tex]

Step-by-step explanation:

From the question we are told that

  The standard deviation is [tex]\sigma = 0.2 \ ounce[/tex]

   The sample size is  n =  15

    The population size is N = 500

     The sample mean is  [tex]\= x = 11.75 \ ounce[/tex]

    The population mean is  [tex]\mu = 16\ ounce[/tex]

From the question we are told the confidence level is  95% , hence the level of significance is    

      [tex]\alpha = (100 - 95 ) \%[/tex]

=>   [tex]\alpha = 0.05[/tex]

Generally the null hypothesis is  [tex]H_o : \mu = 16[/tex]

Answer:

- π is the area of a circle of radius 1

-  π is the circumference of a circle of diameter 1

- π is the constant of proportionality relating the diameter of a circle to its circumference

Step-by-step explanation:

Area of a circle = πr² or πd²/4

Circumference of a circle = 2πr or πd

r is the radius

d is the diameter

If radius = 1

Area = π(1)²

Area = π

hence π is the area of a circle of radius 1 is CORRECT

Given d = 1

Area = πd²/4

Area = π(1)²/4

Area =  π/4

Hence π is the area of a circle of diameter 1 is INCORRECT

For the circumference;

C = 2πr or πd

If r =1

C = 2π(1)

C = 2π

Hence π is the circumference of a circle of radius 1 is INCORRECT

Also if d = 1;

C = πd

C = π(1)

C = π

hence  π is the circumference of a circle of diameter 1 is CORRECT

Since C = πd, then π is the constant of proportionality relating the diameter of a circle to its circumference is CORRECT

Answer:

The correct p-value is 0.106.

Step-by-step explanation:

The information provided is as follows:

The degrees of freedom are:

k - 1 = 5 - 1 = 4

n - k = 10 - 5 = 5

Compute the p-value using Excel as follows:

[tex]p-value=P(F_{(k-1,n-k)}>3.4)\\\\=P(F_{(4,5)}>3.4)\\\\=F.DIST.RT(3.4,4,5)\\\\=0.106[/tex]

Thus, the correct p-value is 0.106.

Answer:

2/ 5

Step-by-step explanation:

From the venn diagram, find tbe probability ;

P(work | sport)

Recall :

P(A | B) = P(A n B) / P(B)

From the venn diagram :

P(work | sport) = P(work n sport) / P(sport)

P(work n sport ) = 4

P(sport) = 6 + 4 = 10

Therefore,

P(work | sport) = P(work n sport) / P(sport)

P(work | sport) = 4 / 10

P(work | sport) = 2/5

Answer:

9) 27

10) 98

Explanation:

Plug in the given variables into each equation. The first equation should be 5(4)+7. Multiply 5 and 4 to get 20+7. Add the like terms to get 27. Substitute 2 for n and the second equation should be 90+2^3. 2^3 should be 8 and 90+8=98.

Answer: A whole number.

Step-by-step explanation: This is because the numerator and the denomenator are both the same. Meaning, we can change it into a whole number, which is 1.

Answer:

Answer:

x = -2i and x = 2i

x = 3 and x = - 3

Step-by-step explanation:

x^4 - 5x^2 - 36 = 0

let u = x^2 and substitute

we have:

u^2 - 5u - 36 = 0

(u - 9)(u + 4) = 0

u = 9 and u = - 4

substitute back for u

x^2 = 9

x = 3 and x = - 3

x^2 = -4 -- i am going to assume you've learned imaginary numbers; otherwise, you cannot take the square root of a negative number.

x = -2i and x = 2i

Answer:

  about 100 years

Step-by-step explanation:

2020 -1920 = 100

Outdoor lights were made safe about 100 years ago. (using information given in the problem statement)

_____

Additional comment

2020 -1930 = 90. So, the actual length of time is between 90 and 100 years.

Using additional research, we find mercury vapor lights were made to have a practical color in about 1929, so 91 years ago. They were invented somewhat before the 1920's but had a greenish color. Fluorescent phosphor coating was added in 1929 to make them produce a whiter light.

Answer:  D) 32.8

=======================================================

Work Shown:

We'll apply the tangent ratio

tan(angle) = opposite/adjacent

tan(64) = x/16

16*tan(64) = x

x = 16*tan(64)

x = 32.8048614652688

x = 32.8

Make sure your calculator is in degree mode. One way to check is to compute tan(45) and you should get 1 as a result.

Answer:

2.47g

Step-by-step explanation:

Given that Ao=14

A(t)= Aoe^kt

k =2yrs

Considering the function where Ao is the initial substance, k is the rate of decay and t is the time.

At the 2nd year A(t) is 7

That is,

7 = 14e^2k

Solve for k

7/14 = e^2k

In(7/14) = 2k

k = In(7/14)÷2

k = In(0.5)/2

k = -0.34657

Hence, A(t)= 14e^-0.34657

So, when t is 5

A(5) = 14e^-0.34657×5

= 2.4749

Approx = 2.47g

Answer:

(D) I think

Step-by-step explanation:

Lets look at our answer choices; A.

The intervals are not comparable. The shorter bar spans more than 10 years. When it comes to a horizontal axis it doesn't matter how far it expands,just if it's expanded correctly.

B.The intervals are appropriately labeled. There not it goes from 25 to 50 in just in instant few climbs up.

C.The intervals are not comparable, but the data on the graph is not misleading. It is misleading the graphs are incorrectly labeled.

Which brings us to our answer D.The vertical axis does not have an appropriate scale. it goes from 0-25 25-50 and 50-75 then 75-100. that's a short distance for such numbers that are pretty far apart.

I hope I'm right and I hope this helps:)!

Answer: A: the intervals are not comparable. The shorter bar spans more than 10 years

Step-by-step explanation:

edge 2021

For this problem, 0.25 in = 50 m. So

11 in = (11 in) • (50/0.25 m/in) = 2200 m

Alternatively, if 0.25 in = 50 m, that means 1 in = 200 m. So 11 in = 11 (200 m) = 2200 m.
